I've heard people call Waltz (music) either 华尔兹 or 圆舞曲, but I've only heard people call Waltz (dance) 华尔兹, never 圆舞.
According to Baidu, 圆舞 does have a meaning of Waltz (dance). It has another meaning of some country/ceremonial dance, seems to suggest this word had been existed before Waltz was imported.
I see this word used as 亦舒's book title, but having not read that book, I don't know if the usage is captured from real life experience or rather fictitious.
Since I've never heard this word used in my daily life, not even from the elders, I am wondering if this word is still used at all. If yes, in which Chinese-speaking region is it used and which meaning of the two does it refer to? If no, was this word ever a common word (when?) and which meaning was it used for?
